An Approach to Calculate Leakage Flow, Stiffness and Damping of Annular Seals in Turbulent Flow Using Lubrication Theory, Part I: Analysis

This paper presents a general theoretical approach to evaluate the leakage flow, stiffness and damping of annular seals in turbulent flow regime including fluid inertia using turbulent lubrication theory. Fluid inertia effect has been incorporated by perturbing the pressure and fluid velocities foll...
